nah man reddit aint all that, you're actually pretty good, it's probably alright having a 13 inch plant after a month. a bigger plant has more internodal space for bud anyway right ? the main idea is that you want your LEDs much lower like around 14 inches from the canopy of your plant, and your HIDs around 24 inches from the canopy of your plant. Even a one inch difference means that the plant will get a lot less light, so you want to keep that dialled in. Pretty much as simple as that homie, more light the plant gets the less it stretches towards the light. does that make sense ? hope this helps ! 🚀
